Does a bad modulator cause hard shifting when car changes gears.
The symptoms happen when car is hot or cold. The gears shift hard when changing; it started about a week ago. There is a warning light on, I believe, that is a suspension light, no check engine light is on or any other warning lights. The problem occurs when I am driving the car.
